attention to safety and take corresponding driving measures; and if
the onboard-terminal calculates an impact on the surrounding
onboard-terminals through its position, speed, and acceleration
information, the onboard-terminal immediately transmits the
information to the surrounding onboard-terminals to prompt the
surrounding onboard-terminals to pay attention to safety and take
corresponding driving measures.
Under the cooperation of the cloud server and the onboard-terminal,
the cooperative communication among the current onboard-terminal,
the surrounding onboard-terminals, and the cloud server is
realized, self-safety is ensured, possible dangers are early
warned, and corresponding traffic density is informed to each
onboard-terminal in advance, so that the traffic is safer and more
intelligent.

DETAILED DESCRIPTION OF EMBODIMENTS
It should be pointed out that the following detailed descriptions
are all exemplary and aim to further illustrate the present
application. Unless otherwise specified, all technical and
scientific terms used herein have the same meanings generally
understood by those of ordinary skill in the art of the present
application.
It should be noted that the terms used herein are merely for
describing specific embodiments, but are not intended to limit
exemplary embodiments according to the present application. As used
herein, unless otherwise explicitly pointed out by the context, the
singular form is also intended to include the plural form. In
addition, it should also be understood that when the terms
"include" and/or "comprise" are used in the specification, they
indicate features, steps, operations, devices, components and/or
their combination.
As shown in FIG. 1, a traffic safety and organization system based
on region block technology according to the present invention
includes: a cloud server 10 and onboard-terminals 20.
The cloud server includes a first communication module 101, a first
processor 102, a first storage module 103, and a first
human-computer interaction module 104.
Wherein, the first communication module 101 is used for the
communication with each onboard-terminal, including transmitting
data and receiving data transmitted by the onboard-terminals.
The first processor 102 processes the received data through a
built-in processing program.
The first storage 103 is used for storing relevant information.
The first human-computer interaction module 104 is used for
displaying the relevant information to relevant personnel.
As shown in FIG. 2, the onboard-terminal 20 includes a second
communication module 201, a second processor 202, a second storage
203, a positioning module 204, and a second human-computer
interaction module 205.
Wherein, the second communication module 201 is used for the
communication with the cloud server.
The second processor 202 is used for processing its data and
information received from the cloud server, from a region block,
from a driver and from passengers.
The second processor 203 is used for storing relevant
information.
The positioning module 204 is used for performing real-time
positioning at a program-indicated time point or within a
program-indicated time interval, and transmitting the positioning
information to the second processor 202.
The second human-computer interaction module 205 is used for
displaying the relevant information to relevant personnel.
The operating method of the present invention is as follows:
As shown in FIG. 4, after the vehicle is started, the
onboard-terminal is started, the positioning module 204 locates its
position and transmits the position information to the second
processor 202, a processor module of the onboard-terminal
calculates its position, speed, acceleration and driving safety
level according to the position and time, transmits these
calculation results to the second storage 203 for storage and the
second communication module 201, and the second communication
module 201 transmits them to the cloud server.
As shown in FIG. 3, after receiving the information of the vehicle,
the cloud server determines whether the vehicle is a high-grade
vehicle. If the vehicle is a high-grade vehicle (e.g., a police
vehicle, an ambulance, a fire vehicle, a road administration
vehicle, etc.), the cloud server, based on a program-defined
algorithm, broadcasts the information of the vehicle such as
communication address and position, speed, acceleration and driving
safety level to corresponding vehicles along the way, in order to
remind the corresponding vehicles of avoiding. Whether the vehicles
are in an accident state, the number of vehicles in the accident
state and the severity of the accident are calculated again
according to the internal algorithm of the cloud server, and the
corresponding information is timely fed back to a general command
center through the first human-computer interaction module 104, to
launch an emergency plan timely. In addition to this, the cloud
server calculates the number of vehicles ahead of and following the
current vehicle within a safety time, and sends communication
addresses of the onboard-terminals of these vehicles to the current
vehicle.
As shown in FIG. 5, after receiving the information sent by the
cloud server, the onboard-terminal collects statistics on the
communication addresses of onboard-terminals of response vehicles
that may affect the driving of the current vehicle within the
safety time in such information, and sends to them a message
requesting to establish a connection, and after the other vehicles
receive the request, they make a determination and establish a
connection, thus forming an initial region block network.
Within the time duration of T<=f1 (safety level), the
onboard-terminal cyclically broadcasts its position, speed,
acceleration, and driving safety level information to all
communication terminals within a region block, and processes the
acquired position, speed, acceleration, and driving safety level
information of all the communication terminals within the region
block through embedded software; if a vehicle affecting the current
vehicle is found, then the human-computer interaction module of the
onboard-terminal of the current vehicle gives feedbacks to its
driver and passengers, e.g., an alarm "Pay attention to the right
rear overtaking vehicle of 140 km/h at 100 m", or "Pay attention to
the ahead vehicle at 100 m that is changing lanes and
decelerating".
Within the time duration of T<=f2 (safety level), the current
vehicle cyclically broadcasts its region block communication
address and cyclically broadcasts the position, speed,
acceleration, and driving safety level information of each
communication terminal, and processes the acquired corresponding
information transmitted by other vehicles in the region block at
the same time; if the vehicle position, speed, and acceleration
calculated would affect the current vehicle within a certain time,
the communication address is superposed on the region block of the
current vehicle; and if no affect is caused, the communication
address is ignored.
If the current vehicle itself perceives that it will affect the
surrounding vehicles during driving, the current vehicle sends
information to the corresponding vehicles affected, to prompt them
to pay attention to the safety, superposes the received information
sent by the other vehicles with warning information calculated by
software of current vehicle at the same time, and feeds back the
superposed information to the driver or passenger through the
human-computer interaction module of the onboard-terminal.
Described above are merely preferred embodiments of the present
application, and the present application is not limited thereto.
Various modifications and variations may be made to the present
application for those skilled in the art. Any modification,
equivalent substitution, improvement or the like made within the
spirit and principle of the present application shall fall into the
protection scope of the present application.
